Cold-formed Steel Sheet Piles 

Cold-formed steel sheet piles continuously cold-bend the steel strip to form Z-shaped, U-shaped or other shapes of cross-section, which can be connected to each other through locks. There are two types of non-bite type cold-formed steel sheet piles (also called channel plates) and bite-type cold-formed steel sheet piles (divided into L-type, S-type, U-type, Z-type). Production process: The thin plate (commonly used thickness 8mm ~ 14mm) is continuously rolled and formed in the cold bending unit. Advantages: less investment in production lines, lower production costs, and flexible product sizing control. Disadvantages: The thickness of each part of the pile body is the same, the section size cannot be optimized, resulting in an increase in the amount of steel used, the shape of the locking part is difficult to control, the joints are not tightly buckled, and the water cannot be stopped, and the pile body is prone to tearing during use.

Hot-rolled Steel Sheet Pile

The hot-rolled steel sheet pile has a tight water barrier with its lock bite. The world's hot-rolled steel sheet piles mainly include U-type, Z-type, AS-type, H-type and dozens of specifications. Production process: It is formed by high temperature rolling in a section steel rolling mill. Advantages: standard size, superior performance, reasonable cross-section, high quality, and tight water-resistance for locking. Disadvantages: technical difficulty, high production cost, inflexible specification series.

Common Specifications of U-shaped Steel Sheet Pile

The locks of the Z-type steel sheet pile are symmetrically distributed on both sides of the neutral axis, and the web is continuous, which greatly improves the section modulus and bending stiffness, and ensures that the mechanical properties of the section can be fully utilized. Because of its unique cross-sectional shape and reliable Larssen lock.

L-type steel sheet pile

L type is mainly used for the support of embankments, embankment walls, trenches and trenches.

Advantages: The section is light, the pile wall occupies less space, the locks are in the same direction, and the construction is convenient. It is suitable for excavation and construction of municipal engineering.

Linear Steel Sheet Pile

Another form of linear steel sheet pile, because of its low height, is close to a straight line, so it is more suitable for excavating some ditches, especially when the space between two buildings is not large and it is necessary to excavate.
